,GAS-COLLECTING MEANS.

Application filed October 4, 1919. Serial No. 328,522.

To (17/ whom if may cancer/1 Be it known that 1, CiIARLns hlollv'rlmi. acitizen of the United States, and resident of llrook'lyn, in the countyof Kings and State of New York. have invented certain new and usefulImprovements in Gas-(ollet-ting- Means. of which the following is aspecification.

The general object of my invention is to provide improved gas collectingmeans for retorts. and particularly for by-productcoke Fig. is a sectionon the line 2-2 of Fig. l

Fig. 3 18 a partial section on the line 33 of Fig. but with the valveremoved; and

Fig. 4C is a partial section on the line lof Fig. l. In the drawings Arepresents one Of the coking chambers or ovens proper of a byproductcokc oven battery of standard present day type. Connected to the usualgas outlet A in the roof of the retort is an, ascension pipe B formed asusual of a cast iron section and comprising a vertical portion and ahorizontal portion connected to the collecting n i ain C which is Iormedofmetal plate and runs lengthwise of the battery and separatelyconnected to all the ovens thereof in the usual manner. A. cleanoutopening normally closed by a door B is provided in the convex side ofthe elbow connecting the horizontal and vertical branches of theascension pipe. Y

The section l3 forming the outer end of the horizontal portion of theascensionpipe is secured to the side of the collecting main so as toopento the latter through a lateral opening C in the collecting main.Advantageously. asshown'. the end of: the sec.- tion 1) projects throughthe opening C and the section is formed with flanges B and B riveted tothe side and top walls respectively of the collecting main.

' At the extreme end of the section B a seat is formed for a slidingvalve member D which is inserted and withdrawn through a kerf or slot(see Fig. 3) formed in the section B projecting over the top of thecollecting main. Grooves 13 formed in the opposite side walls of thesection B below the kert B constitute a guideway tor the valve D.Advantageously; the ribs B forming the front walls oi the grooves P) arecut away as indicated at it somewhat above the bottom portion B of thevalve seat.

The valve D may be drawn out of the section B to connect the ascensionpipe to the collecting main by any suitable means' As shown. a portablejack E is provided for this purpose. the jack comprising a liftingelement terminating in a hook E adapted to enter an eye D formed in theexternal end of the valve member. \Vhen the valve D is put in place itmay be hammered to its seat and the external joints between the valve Dand the walls of the kerf B may, be luted with lire clay. When thevalvemember 1) is withdrawn. the kert' B may be closed by lilting clay alone.but preferably a removable slot closing member F is then inserted in thekert as shown in Fig. 3

and the joints between it and the section B sealed by luting clay.

Those skilled in the art will readily recognize that the constructionillustrated and described possesses important practical advantages a ndovercomesdifficulties hereto fore experienced. and arising from thesevere conditions to which such apparatus is subjected in use. I

In particular the hardened pitch and carbon deposits baking on the valveseat when the ascension pipe is in tree communica-' tion with thecollecting main. as it is during the greater portion of the time. cannotprevent the valve from being inserted and properly seated. The form andcharacter of the valve and valve seat insure that the valve will cutaway enough of these deposits to permit the valve to seat when it ishammered home. The cutting away ot the ribs 15 permits the ready escapeinto the collecting main of the deposits cutout of the grooves it by thevalve as the latter is forced home. Furthermore. the projection of thebottom B oi? the valve seat beyond the tion of the ascension pipedirectly into the side of the collecting main and the character andarrangement of the cut-off valve permits the use of an ascension pipehaving ahorizontal portion of mlmimum length. The :torm and locatlon ofthecut-off valve also minimizes stresses arising from the opening andclosing of the valve and tending to open joints in the ascension pipe orits connection to theoven. a 1

While 1n accordance with the provisions of i the statutes I haveillustrated and described thebest embodiment of my invention now knownto me, it will be apparent to those skilled in the art that changes maybe made in the form of apparatus disclosed without departingfrom thespirit of my invention as set forth in the appended claims. and thatunder certain conditions some features of my invention may be used toadvantage without a corresponding use of other features. I v 1 Havingnow described my invention what I cl; im as new, and desire to secure byLetters Patent, is: 1. In combination a formed with a lateral openingadjacent its top, an ascension pipe having a horizontal portion securedto saidmain in register, with said opening and formed with a at its-endadjacent the main for .a

collecting A main vertically directly intothe stream in its top wall andguidewav a collecting main lateral open ng ad acent its an ascension ppe having a horizontal portion secured to said main in register withsaid opening and formed with a guideway at its end adjacent the main fora vertically movable cut-off valve and a valve in said guicleway, said Alower endint'o said collecting main.

13. In combination formed with a lateral opening adjacent its top, anascension pipe having a horizontal portion projecting through saidopening and formed with a vertical guideway within the collectingmain'and with a slot at its top. a valve inseitable in and removablefrom said guideway through said slot.

4. In combination a collecting main formed with a lateral openingadjacent itstop, an ascension pipe having a horizontal portionprojecting through said opening and formed within the collecting mainwith grooves in its opposite sides and with a slot a valve insertableand removable through said slot and having its edges received in saidgrooves when inserted, the front walls of said grooves tm'niinatingabove the bottom of said liorizi'mtal portion.
